NFV thriving: CT vendors are increasingly favoured by telcos

The near we come to 5G network deployment, the more we see global mainstream telcos concentrating on the research and deployment of SDN and NFV. According to the latest survey by TBR Research, most tier-one telcos are going to adopt SDN and NFV technology in two years. The NFV concept that has been proposed for 10 years, is designed for the purpose of network transformation. Telcos are suffering high network costs due to massive investment in equipment and complications of network operation and maintenance (O&M). Even worse, closed telecom services and long lead times for new services make it more difficult for telcos to handle OTT services. Telcos must re-examine traditional technology systems and business approaches, and SDN and NFV attract high degrees of interest, as they claim to solve problems of high costs, closure and complicated O&M. SDN and NFV are complementary. They develop in parallel to make the network more flexible and enable telecom network architecture to be easily upgraded. Over the past two years, global telcos have developed their transformation strategy, focusing on network re-architecture, and hope to occupy a favorable position in the future network development pattern. NFV is therefore now on the verge of large-scale deployment. However, although telcos intend to use SDN and NFV technologies within the next two years, they are still hesitant when deploying NFV. Why is this? Although NFV is a cutting-edge, disruptive technology, capable of making CPSs’ network architecture more open and service deployment more flexible, it still faces a lot of challenges…
